Which of the following technologies is supported by the majority of cloud providers in order to support the orchestration of containerized applications?

Kubernetes has become the industry standard for container orchestration and is supported by virtually all major cloud providers to manage and scale containerized applications. Its open-source nature and powerful features for deployment, scaling, and management have driven this widespread adoption.

Vagrant is primarily used for creating and managing virtual machine development environments locally, not for cloud container orchestration.

Ansible is a configuration management and automation tool, used for provisioning and orchestration, but not specifically for container orchestration at the platform level like Kubernetes.

Terraform is an Infrastructure as Code (IaC) tool used for provisioning and managing cloud infrastructure, but it provisions the underlying resources for container orchestration platforms, rather than being the orchestrator itself.
